I'd have to actually see the study before I could refute it. The article conveniently left virtually all relevant information out, including where it was published, if it was peer-reviewed, what the parameters of the study were, etc.
I will say this though: Traci Mann is a psychologist, not a metabolic science professional, not a weight loss expert. She's also the one who wrote the laughable paper that claimed that there is no such thing as comfort food.
